Title: Mounting structure for semiconductor device and mounting method therefor
Inventor: SAKURAI MASAYA
IPC: H05K3/34
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To relax thermal stresses concentrating on solder bumps and to thereby prevent break of the solder bumps due to thermal fatigue, by providing a mounting board and solder bumps to be mounted on electrodes of the mounting board having the solder bumps with uniform voids. SOLUTION: A wet back step is performed by setting a wet back melting temperature to a temperature lower than the melting point +20 deg.C and higher than the melting point +10 deg.C of solder. Countless voids 14 are uniformly formed within a molten solder bump 15. Let us think about the case where a thermal load is applied to a semiconductor device 11 to thereby produce a thermal stress at the bump 15. A gas is present within each void 14, and if it is assumed, e.g. that air is present within each void, the modulus of elasticity of each void is 0.33 MPa, which is a value negligible compared with that of the solder. It means that the voids 14 have formed free surfaces at all the parts of the bump 15, and thus any displacements within the bump 15 are absorbed by the voids 14.  As a result, the capability of relaxing produced thermal stresses is increased, and thus the life of the solder bump against thermal fatigue can be improved.
